4 Claims.

The present application is a division of Serial No. 71,768 filed on March 30, 1936.

This invention relates to an improved air conditioning apparatus by means of which ozone may be produced and fed into a room to mix with air therein and serve to purify the same.

Another object of the invention is to permit the variable source of ozone to be easily adjusted by an adjusting device having an actuating member disposed externally of the housing where it is readily accessible.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:

Figure 1 is a fragmentary view partially in section and partially in elevation of a construction wherein a single rotatable cylinder is used for a variable source of ozone, and

Figure 2 is a view taken along the line 9-9 of Figure 1.

In Figures 1 and 2, there has been illustrated a form of variable ozone generator. This form of generator has only one ozone producing cylinder which is indicated by the numeral 9| and the shaft 92 thereof carries a spiral spring 93 having one end anchored to the shaft and its other end secured by a pin 94 so that when the cylinder is turned in one direction the spring will be wound to tension it and act as a rewind spring.

An inner electrode consisting of a cylindrical screen 95 fits into the cylinder 9| and externally of this cylinder there has been mounted a curtain 95 of metal links and serving as an outer electrode. This curtain extends under the cylinder 9| and then upwardly and over a cylinder 91, the shaft 98 of which projects outwardly through the wall of the housing and carries a turning knob 99 having a dial I08 associated with it so that turning of the cylinder by its knob may be accurately gauged.

When the cylinder is turned in one direction the curtain will be unwound from the cylinder 9| and onto the cylinder 91, and during this time the spring will be wound and tensioned so that when the knob is turned to rotate the cylinder 91 in an opposite direction, the spring will impart rotation to the cylinder 9| and the curtain will be wound thereon. Therefore, the variable ozone generator may be adjusted to produce the desired quantity of ozone.

While but one form of the invention has been herein shown and described, it will be apparent to those skilled in the art that various minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.

What is claimed is:

1. An ozone generator consisting of a cylinder of insulating material rotatably mounted, a shaft extending axially through the cylinder, a cylindrical metal screen fitting snugly within the cylinder and constituting an inner electrode, a metal curtain constituting an outer electrode and secured at one end against the outer face of the cylinder, a winding spring coiled about said shaft with one end anchored to the shaft and its other end anchored to the cylinder whereby the spring will be wound and tensioned when the cylinder is rotated in a direction to unwind the curtain, a second cylinder rotatably mounted and having the other end of the curtain secured thereto, and means for rotating the second cylinder in a direction to wind the curtain thereon and unwind the curtain from the first cylinder.

2. An ozone generator consisting of a frame, a cylinder carried by said frame and having a cylindrical body of glass and caps of insulating material closing ends of the body, a shaft ex tending axially through the body and supported by said frame, a cylindrical metal screen in said body in close contact therewith and constituting an inner electrode, an outer electrode consisting of a metal curtain fixed at one end to the body and adapted to be wound upon the body when the body is rotated in one direction, a contact extending into the body and having an arm within the body extending radially thereof and making contact with the inner electrode, the curtain being grounded upon the frame, and. means for turning the cylinder to an adjusted position and maintaining the same in the set position with the curtain wound upon the cylinder to a predetermined extent.

3. An ozone generator consisting of a cylinder having a cylindrical glass body, heads of insulating material at the ends of said body, end portions of the body being embedded in the heads and marginal portions of the heads being extended along the outer surface of the body. a shaft extending axially through the body and heads, a metal sleeve about the shaft projecting outwardly from one head, a cylindrical metal screen fitting snugly within the body and constituting an inner electrode, an arm extending radially from said sleeve within the body and having a bent outer end bearing against the metal screen, a metal strip extending longitudinally of the body against the outer face thereof with its ends embedded in the extended marginal portions of the heads, a' curtain of metal, tongues extending from said strip and engaged through one end portion of the curtain whereby the curtain is connected with the strip and constitutes an outer electrode adapted to be Wound about the body when the cylinder is rotated in one direction, and a metal strip having tongues engaged through the other end portion of the curtain and constituting means for connecting the last mentioned end of the curtain with a frame supporting the cylinder.

4. An ozone generator consisting of a frame, a cylinder carried by said frame and having a cylindrical body of glass and caps of insulating material having air vents closing ends of the body, a shaft extending axially through the body and supported by said frame, a cylindrical metal screen in said body in close contact therewith and constituting an inner electrode, an outer electrode consisting of a metal curtain fixed at one end to the body and adapted to be wound upon the body when the body is rotated in one direction, a contact extending into the body and having an arm within the body extending radially thereof and making contact with the inner electrode, the curtain being grounded upon the frame, and means for turning the cylinder to an adjusted position and maintaining the same in the set position with the curtain wound upon the cylinder to a predetermined extent.
